You need to write a function that does a runtime view switching. Most
probably that function will reside in the frame. Suppose the number of views
is two; A typical function might look like so;

void CMainFrame::SwitchToView(int nView)
{
    CView* pOldActiveView = GetActiveView();
    CView* pNewActiveView = (CView*) GetDlgItem(nView);
    if (pNewActiveView == NULL)
    {
        switch (nView) {
        case m_nView1:
            pNewActiveView = (CView*) new CFirstView;
            break;
        case m_nView2:
            pNewActiveView = (CView*) new CSecondView;
            break;
        }
        CCreateContext context;
        context.m_pCurrentDoc = pOldActiveView->GetDocument();
        pNewActiveView->Create(NULL, NULL, WS_BORDER | WS_CHILD,
CFrameWnd::rectDefault, this, nView, &context);
        pNewActiveView->OnInitialUpdate();
    }

    SetActiveView(pNewActiveView);
    pOldActiveView->SetDlgCtrlID(pOldActiveView->GetRuntimeClass() ==
RUNTIME_CLASS(CFirstView) ? m_nView1 : m_nView2);
    pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
    pOldActiveView->ShowWindow(SW_HIDE);
    pNewActiveView->ShowWindow(SW_SHOW);
    RecalcLayout();
}

where m_nView1 and m_nView2 are some constants, e.g. 1 and 2 respectively.

I created an SDI application, and I replaced the default View class
in the call to create CSingleDocTemplate with a derivative of
CFormView.

This works and shows my form, but occasionally I want the form to
change
on the fly. How do people typically change the form in CFormView
on the fly?
